There are different syntaxes so here's how you do it using wild
pattern-matching:
In [15]: expr = (a*x**14 + b*x + c)
In [16]: expr
Out[16]:

a⋅x + b⋅x + c
In [17]: w = Wild('w'
Hi everyone,
My name is Jingze Dai and I am a CS student from McMaster University,
Canada. I want to be a developer in the sympy group. But I do not know
after learning, where should I get started? Can anyone give me some
suggestions?
Thank you so much
Sincerely
David

Dear group,
A substitution like this is easy to make with SymPy:
(a*x**2+b*x+c).subs(x,y)
However, how can I make a conditional substitution, such as:
a) One that would replace even powers of x only.
b) One which would replace even powers of x by y**(n/2) resulting in
a*y**7+b*x+c? I.e. one
